Former Dallas Cowboys star Michael Irvin is showing a lot of faith in Herschel Walker , the retired football player who is now running for the U.S. Senate seat in Georgia . Speaking with Fox News, Irvin said Walker believes he can do anything, including taking down Mike Tyson in a fight . “I never doubted Herschel in anything that he has done,” Irvin told Fox News . “One of the first things Herschel said to me was, ‘Mike, you know, I really think I could beat Mike Tyson,’ This was when Mike Tyson was hitting you in the head, and your whole body just exploded. I said, ‘Dude, why you talking like this? What is this? Some death wish? What are you talking about?’ But he was dead serious.”
